PBGTR: PRICE BASED GAME THEORY ROUTING FOR MINIMUM COST ROUTING PATH IN MANET

Abstract

In MANET, when a mobile node needs to communicate with a remote destination, it relies on the other nodes to relay the packets. This multi-hop packet transmission can extend the network coverage area using limited power and improve area spectral efficiency. Since the mobile nodes are battery driven and one of the major sources of energy consumption is radio transmission, selfish nodes are unwilling to lose their battery energy in relaying other users’ packets. To tackle this problem, this paper proposed a novel price based game theory routing (PBGTR) algorithm in MANET. Using this routing algorithm, a source node finds Minimum Cost Routing Path (MCRP) within destination node, then forward packet to destination via this MCRP. After the successful transmission, a source node pays the payment to each participated nodes. The simulation results shows that the proposed PBGTR routing algorithm is more efficient than other existing routing protocols. Furthermore, it consumes minimum cost for routing.
